first time spray booth question?

ive been shooting paint for like 4 years now, but never in a real booth. well this weekend i rented one for $50.00 for 4 hours. i was wondering, are there any tips or suggestions that would best utilize my time in there. also, ive been spraying in garages with limited ventilation, how will a booth differ from garages? quality of final finish? drying time? time between coats? im spraying a bc/cc paint system. any info will be greatly appreciated. thanks

You will never want to go back! Booths are a dream to work in. Drying time , time between coats, etc., wont change. Neither should your paint routine of wetting down the floor, de-greasing the primer, tack-ragging the surface, etc. However the lighting will be super so your coverage will be more uniform and job quality much improved. Final surface will be much cleaner too.

Actually the time between coats and drying time can be speeded up of course because of the air movement pulling the solvents from the paint film.

The most important thing you can do is depending on the clear find out how long the manufacturer wants you to run the fan after your last coat of clear.

Not long enough on some clears it can cause dieback, solvent pop and even lost of adhesion between the clear and the base.

To long on some it can cause cloudiness or solvent pop.
Very important that you know.

I'll agree with the guys that you won't want to go back to the garage, the lighting should be far superior, as well as good exhaust. Less shadows and better lighting means you should have an easier time reading how the paint is laying and how far you can push it so everythings nice smooth and glossy, but not full of runs. Shouldn't be doing any guess painting like in many garages with a lack of light. Theoreticly you should have a cleaner job also, but it really depends on the booth and how well its upkeep is. I've had cleaner jobs out of my garage then could get in some of the crossflow booths I worked in, even when cleaning them well often. Then there was the one in school which was downdraft and a real dream to paint in. Its kinda sucks starting out in a real nice booth and then spending most of you time painting in lesser quality ones for years after that. At least for you going from a garage to a booth should be an improvement. Don't really know what to suggest to save time, besides having stuff all ready for your time in the booth and and making sure you have everything you need, tack rags, mixing cups, what ever you feel you are going to need and normally use. Even little things like stretching out the hoses before you start so you don't get a tangled mess to drag around the car, or making sure there is something to stand on if you will need to reach the center of the roof. No sense in rushing things though, cause thats when screwups happen and can not only ruin the job, but your time very well may be used up before you can fix and finish the job. Thats one advantage to your garage, you have time without worring about having to share it.

A helper outside the booth to mix the paint, like a runner for you.

Yes indeed you will love the booth. But, is it a down draft or a cross flow. In "picky world" that changes your pattern around a car. In a down-draft I start at the top and work my way down and around (ie. R roof, L roof, R qrtr, deck, L qrtr, R door, L door, R fndr, hood, L fndr). In a cross-draft I start at one end and run back and forth down the sides (ie. R qrtr, deck, L qrtr, R roof, L roof, R door, L door, R fndr, hood, Lfndr). Try to avoid overspray being drawn over the coat as it flashes behind you. Just my opinion, and it has worked for me.
